Abstract: PURPOSE: A circuit of synchronization for small signal testing is provided to increase the testing accuracy without being affected by many noises by synchronizing the testing signal of the object to be tested with a reference signal from the initial source. CONSTITUTION: In the circuit of synchronization for small signal testing, a signal detecting unit(60) conducts a synchronization detection by multiplying the testing signal obtained after a source signal of the source is given to the object to be tested with the reference signal having a regular waveform of the source. A low pass filter(70) eliminates the AC element from the output signal for the signal detecting unit(60). Thus by the synchronization, the testing result is not affected by external noises.

Abstract: PURPOSE: A method for forming wires is provided to prevent generation of a step due to a connection line by making a passage in which a wire connection line will be formed by wet etching method and then forming the connection line between neighboring wires or neighboring contacts in the passage. CONSTITUTION: A method for forming wires prepares an insulating substrate(31) in which a wire and a portion where a wire connection line will be formed are each defined. The first insulating film is formed on the insulating substrate at a portion where the wire connection line will be formed and a wide portion between the wires. The second insulating film(33) having an etch ratio to the first insulating film is formed on the entire surface. The second insulating film(33) and the first insulating film are selectively etched to expose the insulating substrate only at a portion where the wires will be formed. The first insulating film is wet-etched to secure a wire connection line formation space between the insulating substrate and the second insulating film. A tungsten layer is formed on the entire surface. The tungsten layer is blanket-etched so that the tungsten layer can remain lower than the second insulating film, thus forming the wires and the wire connection line. The second insulating film is then removed.

IPC: H04Q7/36
Filed: 1997-08-26
Abstract: PURPOSE: An improved feed-forward multi carrier power amplifier architecture and a novel array antenna are provided to spatially filter unwanted intermodulation products. CONSTITUTION: An improved feed-forward multi carrier power amplifier architecture provides for independent control of unwanted intermodulation products generated in the amplifier. When used in a novel array structure, a separate radiation lobe containing the unwanted intermodulation products may be steered independently from a main radiation lobe. In a cellular base station application, the radiation lobe containing the unwanted intermodulation products may be steered away from the main radiation lobe thereby providing spatial filtering of the unwanted signals. The radiation lobe containing the unwanted intermodulation products may be steered rapidly in time using, for example, a noise like function to provide statistical averaging of the interference in the direction of desired communications.

Abstract: PURPOSE: To improve the gain and noise characteristics of a semiconductor integrated circuit by providing a low-noise amplifier at the position where the distances from outside-package pins to pads become the shortest. CONSTITUTION: A low-frequency-band low-noise amplifier 121 and a high- frequency-band low-noise amplifier 123 are respectively supplied with stable bias currents from their bias circuits 125 and 126. The bias currents are supplied to the amplifiers 121 and 123 after the currents are converted into bias voltages by means of a bias resistor 122 for low-frequency-band low-noise amplifier and a bias resistor 124 for high-frequency-band low-noise amplifier. The circuits of the amplifiers 121 and 123 are arranged between the output pin 103 of the amplifier 121 and the input pin 109 of the amplifier 123 so as to make the distances from the front ends of the outside-package pins of the amplifiers 121 and 123 to pads the shortest. In addition, the grounding pins of the amplifiers 121 and 123 are prevented from being arranged adjacently to each other. Therefore, the adverse effect of transformer coupled connector between the pins can be reduced and, accordingly, the gain and noise characteristics of a semiconductor integrated circuit can be improved.
